Aus Pharmazeutische Technologie, 4. Auflage, 1978, VEB Verlag Volk und Gesundheit, Berlin, Seiten 43 und 44 sowie Seiten 290 bis 293 sind beschrieben die Eigenschaft Hygroskopizität sowie die Herstellung von Granulaten. Es findet sich jedoch kein spezieller Hinweis auf Badesalze.From Pharmaceutical Technology, 4th edition, 1978, VEB Verlag Volk und Gesundheit, Berlin, pages 43 and 44 and pages 290 to 293 describe the property of hygroscopicity and the production of granules. However, it is found no special reference to bath salts.
Aus Fiedler, Lexikon der Hilfsstoffe für Pharmazie, Kosmetik und angrenzende Gebiete, 3. Auflage, 1989, Seite 1328 und Seiten 695 bis 696 ist bekannt, daß Vinylpyrrolidon-Vinylacetat-Copolymere unter der Bezeichnung Kollidon VA 64 unter anderem auch zur Herstellung von Tablettenüberzügen für feuchtigkeitsempfindliche Substanzen einsetzbar ist. Ein Hinweis auf Badesalz findet sich hierin jedoch nicht.From Fiedler, Lexicon of auxiliary substances for pharmacy, cosmetics and adjacent areas, 3rd edition, 1989, page 1328 and Pages 695 to 696 are known to contain vinyl pyrrolidone-vinyl acetate copolymers under the name Kollidon VA 64 under other also for the production of tablet covers for moisture-sensitive substances can be used. On However, there is no reference to bath salts here.
Die Erfindung hat sich die Aufgabe gestellt, ein Badesalz zur Verfügung zu stellen, welches hohe Mengen an Magnesiumchlorid aber keine wesentlichen Mengen an Calciumsalzen enthält.The object of the invention is a bath salt to provide high levels of magnesium chloride but does not contain significant amounts of calcium salts.
Diese Aufgabe ist ausgesprochen schwierig zu lösen, da Magnesiumchlorid stark hygroskopisch ist und bereits durch den Zutritt von Luftfeuchtigkeit zerfließt. Es ist somit nicht möglich, das Magnesiumchlorid in reiner Form trocken und rieselfähig zu halten.This task is extremely difficult to solve because of magnesium chloride is highly hygroscopic and already through the Admission of humidity dissolves. So it is not possible to dry the magnesium chloride in pure form and to keep free flowing.
Es ist jetzt gelungen, ein Badesalz mit einem Gehalt an Magnesiumsalz zur Verfügung zu stellen, welches dadurch gekennzeichnet ist, daß es als rieselfähiges, nicht hygroskopisches Granulat vorliegt. Dieses Granulat aus Kernen besteht aus mindestens 30 Gew.-% Magnesiumchloridkristallen aber keinen wesentlichen Mengen an Calciumsalzen, wobei die Granulatkörner ummantelt sind mit einem wasserlöslichen aber als Wasserdampfsperre wirkenden Filmüberzug.It is now possible to use a bath salt with a magnesium salt content to provide, which is characterized by is that it's as flowable, not hygroscopic Granules are present. This granulate consists of cores at least 30% by weight of magnesium chloride crystals but none substantial amounts of calcium salts, the granules are covered with a water-soluble but as Water vapor barrier film coating.
Aus den Erfahrungen mit Magnesiumchlorid-Salben ergab sich die weitergehende Aufgabe, diesem Badesalz zusätzlich Vitamin E und/oder ungesättigte Fettsäuren zuzusetzen. Da dies lipophile Substanzen sind, bereitet ihre Zumischung zu einem Badesalz besondere Schwierigkeiten.Experience with magnesium chloride ointments resulted in the further task, this bath salt additional vitamin Add E and / or unsaturated fatty acids. Because this is lipophilic Substances are prepared for their admixture Bath salts have particular difficulties.
Es ist jetzt gelungen, Vitamin E und/oder ungesättigte Fettsäuren in Form von wäßrigen Dispersionen einzusetzen und damit die Magnesiumchloridkristalle zu granulieren.It has now succeeded in vitamin E and / or unsaturated fatty acids use in the form of aqueous dispersions and to granulate the magnesium chloride crystals.
Um ein rascheres Auflösen des Badesalzes im Badewasser zu erzielen, hat es sich weiterhin als sehr wertvoll erwiesen, dem Badesalz Sprengmittel und/oder Brausehilfsstoffe zuzugeben. Dies ist insbesondere dann möglich, wenn das Sprengmittel und/oder die Brausehilfsstoffe in den Kernen der Granulatkörner vorliegen und das Vitamin E und/oder die ungesättigten Fettsäuren als Filmschicht zwischen den Kernen des Granulats vorliegen. Um die fettigen und öligen Filmschichten des Vitamin E und/oder der ungesättigten Fettsäuren anschließend mit einem wasserlöslichen aber als Wasserdampfsperre wirkenden Film überziehen zu können, empfiehlt es sich, das Granulat vor der Ummantelung abzustäuben. Besonders bewährt hat sich das Abstäuben mit feinteiligem Magnesiumlaktat, welches nach dem Auflösen des Badesalzes weitere Magnesiumionen für die Therapie zur Verfügung stellt.To dissolve the bath salt more quickly in the bath water , it has continued to be very valuable Add disintegrants and / or effervescent additives to the bath salt. This is particularly possible if the explosive and / or the effervescent aids in the cores of the Granules are present and the vitamin E and / or the unsaturated Fatty acids as a film layer between the cores of the Granules are present. To the greasy and oily layers of film of vitamin E and / or unsaturated fatty acids with a water-soluble but as a water vapor barrier It is recommended to be able to cover the acting film to dust off the granules before coating. Especially Dusting with finely divided magnesium lactate has proven itself, which after dissolving the bath salt more Provides magnesium ions for therapy.
Als Brausehilfsstoffe und/oder Sprengmittel können auch Gemische von Sprengmitteln mit Brausehilfsmitteln verwendet werden. Als Brausehilfsmittel kommen alle üblichen trockenen Gemische in Frage, die keine Calciumsalze enthalten. Bevorzugt verwendet wird das Gemisch aus Natriumhydrogencarbonat und Zitronensäure. Als Sprengmittel kommen vor allem Stoffe in Frage, die bei Berührung mit Wasser stark quellen. Hierzu gehören getrocknetes Agar-Agar und getrocknetes Guargum. Durch die starke Ausdehnung bei der Berührung mit Wasser helfen diese Sprengmittel, die wirksamen Komponenten rasch im Badewasser aufzulösen.Mixtures can also be used as effervescent agents and / or disintegrants of explosives used with effervescent aids become. All the usual dry aids come as effervescent aids Mixtures that do not contain calcium salts. Prefers the mixture of sodium hydrogen carbonate is used and citric acid. Substances are the main explosives in question, which swell strongly on contact with water. For this include dried agar and dried guar gum. Due to the strong expansion when it comes into contact with water these explosives help the effective components quickly dissolve in the bath water.
Da die wichtigsten Komponenten des erfindungsgemäßen Badesalzes Magnesiumchlorid und gegebenenfalls Magnesiumlaktat sind, sollte der Gehalt hiervon vorzugsweise mehr als 50 Gew.-% betragen. Je nach Art und Menge der sonstigen Zusatzstoffe wie Sprengmitteln, Brausehilfsstoffen, Vitamin E und/oder ungesättigten Fettsäuren beträgt somit der Gehalt des erfindungsgemäßen Badesalzes an Magnesiumchlorid 55 bis 95 Gew.-%. Bei Zusatz von Vitamin E und/oder ungesättigten Fettsäuren liegt deren Gehalt zwischen 0,5 und 10 Gew.-%. Mengen von 1,5 Gew.-% Vitamin E und 1 % ungesättigter Fettsäuren haben sich besonders bewährt. Der Gehalt an Sprengmitteln und/oder Brausehilfsmitteln liegt meist im Bereich zwischen 2 und 10 Gew.-%. Ein Gehalt von 5 Gew.-% Brausehilfsmittel hat sich besonders bewährt.Since the most important components of the bath salt according to the invention Magnesium chloride and optionally magnesium lactate the content thereof should preferably be more than 50 % By weight. Depending on the type and amount of other additives such as disintegrants, effervescent aids, vitamin E and / or unsaturated fatty acids is the content of the bath salt of magnesium chloride 55 to 95% by weight. With the addition of vitamin E and / or unsaturated Fatty acids have a content between 0.5 and 10% by weight. Amounts of 1.5% by weight of vitamin E and 1% of unsaturated fatty acids have proven particularly successful. The content of explosives and / or shower aids are usually in the range between 2 and 10% by weight. A content of 5% by weight effervescent aid has proven particularly successful.
Das Granulieren erfolgt vorzugsweise mit einer wäßrigen Suspension von dl-α-Tocopherolacetat in wasserdispergierbarer Form. Die ungesättigten Fettsäuren werden ebenfalls vorzugsweise als solubilisierte Komplexe mit Hydroalcohol eingesetzt. Als ungesättigte Fettsäuren werden vorzugsweise Linolsäure, Linolensäure und Arachidonsäure verwendet. Prinzipiell kommen aber auch alle anderen einfach oder mehrfach ungesättigten Carbonsäuren in Frage, die sich bei der Behandlung des atopischen Ekzems und Psoriaris bewährt haben.The granulation is preferably carried out with an aqueous suspension of dl-α-tocopherol acetate in water-dispersible Shape. The unsaturated fatty acids are also preferred used as solubilized complexes with hydroalcohol. Preferred unsaturated fatty acids are linoleic acid, Linolenic acid and arachidonic acid are used. in principle but also come all other mono- or polyunsaturated Carboxylic acids in question during treatment of atopic eczema and psoriaris.
Die Ummantelung der Granulatkörner mit einem wasserlöslichen aber als Wasserdampfsperre wirkenden Filmüberzug erfolgt beispielsweise mit einem Vinylpyrolidon-vinylacetat-copolymerisat gegebenenfalls unter Zusatz von Hydroxyethylcellulose, Ethylcellulose und/oder pyrogener Kieselsäure. Diese Substanzen lassen sich als alkoholisch-wäßrige Lösung aufsprühen und bilden nach dem Trocknen in Form eines Filmüberzugs einen ausgezeichneten Schutz gegen Feuchtigkeit.The coating of the granules with a water-soluble but acts as a water vapor barrier film coating for example with a vinyl pyrolidone-vinyl acetate copolymer optionally with the addition of hydroxyethyl cellulose, Ethyl cellulose and / or fumed silica. This Substances can be sprayed on as an alcoholic aqueous solution and form after drying in the form of a film coating excellent protection against moisture.
Das erfindungsgemäße Badesalz wird je nach Gehalt an Magnesiumchlorid in Mengen von 200 bis 500 g dem Badewasser (ca. 80 l) zugesetzt. Das Badewasser enthält somit das Magnesiumchlorid in Konzentrationen von weniger als 1 %. Dafür kann es aber über längerer Zeit gleichmäßig von der gesamten Haut aufgenommen werden, so daß es dort seine Wirksamkeit entfalten kann.The bath salt according to the invention is, depending on the magnesium chloride content in quantities of 200 to 500 g the bath water (approx. 80 l) added. The bath water thus contains the magnesium chloride in concentrations of less than 1%. For that can but evenly over the entire skin over a longer period of time be included so that it can develop its effectiveness there can.
Die gute Wirksamkeit des Magnesiumchlorids in dem erfindungsgemäßen Badesalz wurde zunächst getestet an der Hemmung des Crotonöl-induzierten Ohrödems bei Mäusen. Dazu wurden Zubereitungen, die jeweils 10 Gew.-% Magnesiumchlorid enthielten, vergleichend getestet mit aufgelösten Badesalzen, so daß jeweils eine Endkonzentration von ebenfalls 10 Gew.-% Magnesiumchlorid entstand.The good effectiveness of magnesium chloride in the invention Bath salt was first tested to inhibit the Croton oil-induced ear edema in mice. For this purpose, preparations each containing 10% by weight magnesium chloride, comparatively tested with dissolved bath salts, so that each have a final concentration of 10% by weight of magnesium chloride originated.
In dem Vergleich mit einbezogen wurden handelsübliche Badesalze mit einem Gehalt an Magnesiumsalzen und einen dem Toten Meer entsprechenden Gehalt an Calciumchlorid. Weiterhin verglichen wurden wäßrige Lösungen von Magnesiumchlorid und reines Natriumchlorid.Commercial bath salts were included in the comparison containing magnesium salts and one to the dead Corresponding content of calcium chloride. Further compared were aqueous solutions of magnesium chloride and pure sodium chloride.
Bei entzündlichen Hautkrankheiten haben epidermale Langerhans-Zellen
(ELZ) eine entscheidende pathogenetische Bedeutung.
Diese Zellen zählen zu den Antigen-präsentierenden Zellen.
Deren Aktivität wird maßgeblich durch ein Oberflächenenzym
bestimmt, eine ATPase. Die Hemmung dieses Enzyms bewirkt
eine Hemmung der Funktion der ELZ und damit eine verminderte
entzündliche Reaktion auf der Haut. Die Hemmwirkung von
Magnesium, dem erfindungsgemäßen Magnesiumbadesalz und anderen
vergleichbaren Badesalzen und Kochsalz wurden bestimmt.
Die Ergebnisse sind in den nachfolgenden Tabellen 1 und 2
zusammengestellt.

37°C inkubiert, und es wurde nachfolgend die ELZ pro 1 mm2
Epidermis bestimmt.
Erste Beobachtungen bei Patienten mit Neurodermitis und Schuppenflechte mit dem erfindungsgemäßen Badesalz im Badewasser haben sehr gute Erfolge gezeigt. Das erfindungsgemäße Badesalz, insbesondere unter Zusatz von Vitamin E und/oder ungesättigten Fettsäuren, ist somit hervorragend verträglich und wirksam.First observations in patients with eczema and psoriasis with the bath salt according to the invention in bath water have had very good results. The bath salt according to the invention, especially with the addition of vitamin E and / or unsaturated Fatty acids is therefore extremely well tolerated and effective.
Die Herstellung des erfindungsgemäßen Salzes erfolgt dadurch, daß zunächst das Magnesiumchlorid in kristalliner Form mit den Brausehilfsstoffen Natriumhydrogencarbonat und Zitronensäure vermischt wird. Dieses Gemisch wird mit einer wäßrigen Suspension von dl-α-Tocopherolacetat (wasserdispergierbar) und einem Hydroalcohol-solubilisierten Komplex von ungesättigten Fettsäuren (Linolsäure, Linolensäure und Arachidonsäure) auf die Pulvermischung aufgesprüht, wobei dieses granuliert wird. Dieses Material wird mit feinpulvrigen Magnesiumlaktat abgestäubt und anschließend mit einer wäßrigen Lösung von Vinylpyrolidon-vinylacetat-copolymerisat und Hydroxyethylcellulose ummantelt. Nach dem Trocknen hat sich ein Filmüberzug gebildet, der das Granulat gegen Luftfeuchtigkeit schützt und ihm eine hohe Stabilität verleiht. Beim Eingeben ins Wasser löst sich das Badesalz rasch unter leichtem Schäumen auf.The salt according to the invention is produced by that first the magnesium chloride in crystalline form with the effervescent additives sodium hydrogen carbonate and citric acid is mixed. This mixture is mixed with an aqueous Suspension of dl-α-tocopherol acetate (water dispersible) and a hydroalcohol-solubilized complex of unsaturated Fatty acids (linoleic acid, linolenic acid and arachidonic acid) sprayed onto the powder mixture, this granulating becomes. This material is made with fine powdered magnesium lactate dusted and then with an aqueous solution of Vinyl pyrolidone-vinyl acetate copolymer and hydroxyethyl cellulose jacketed.
